The OCTOPLUS 500 EBV system has been developed for the growth of high quality Si/SiGe heterostructures on 4 inch Si substrates. Optionally the system can be upgraded to 6 inch substrate size. The MBE chamber is equipped with two electron beam evaporating guns and up to 8 effusion cells or gas injectors for deposition or surface treatment.
Among the wide range of materials covered by products of Dr. Eberl MBE-Komponenten GmbH we have very detailed knowledge in the group IV elements C, Si and Ge MBE.
Based on many years of active research experience in the field of growth and doping applications with these elements our team develops and manufactures the OCTOPLUS 500 EBV system and all essential components. Each product is assembled and carefully tested in-house.
The beam flux produced by the electron guns can be monitored by cross-beam quadrupole mass spectrometers on the elements employed. The substrate manipulator applies pyrolytic graphite or alternatively tungsten or tantalum heaters. The OCTOPLUS 500 EBV MBE system is field-proven and ideally suited for metals, magnetics, oxides, topological insulators and Si/SiGe heterostructure growth in research and production processes.
Outstanding features of the OCTOPLUS 500 EBV are the high reliability and versatility of the system.
The standard version of the OCTOPLUS 500 EBV comprises 10 radially arranged source ports, from which we recommend 8 ports to be used for effusion cells, sublimation sources or comparable components. Two large ports DN250CF are provided for e-beam evaporation guns. The e-beam evaporators can also be a multi-pocket version EBVM. A rapid pump-down load lock chamber with a horizontal working transfer rod system or a central transfer module allows easy substrate introduction without breaking the vacuum of the MBE chamber.
